Abstract: Aspects of this disclosure relate to a process for rendering graphics that includes performing, with a hardware unit of a graphics processing unit (GPU) designated for vertex shading, a vertex shading operation to shade input vertices so as to output vertex shaded vertices, wherein the hardware unit adheres to an interface that receives a single vertex as an input and generates a single vertex as an output. The process also includes performing, with the hardware unit of the GPU designated for vertex shading, a hull shading operation to generate one or more control points based on one or more of the vertex shaded vertices, wherein the one or more hull shading operations operate on at least one of the one or more vertex shaded vertices to output the one or more control points.

Abstract: Techniques are described for using a texture unit to perform operations of a shader processor. Some operations of a shader processor are repeatedly executed until a condition is satisfied, and in each execution iteration, the shader processor accesses the texture unit. Techniques are described for the texture unit to perform such operations until the condition is satisfied.

Abstract: An example method of filtering in a graphics processing unit (GPU) may include storing, by a texture engine of the GPU, filter coefficients of a filter as a texture memory object (TMO) in a texture cache of the GPU in response to a first instruction. The method may include retrieving, by the texture engine, filter coefficients from the texture cache in response to a second instruction. The method may include storing, by the texture engine, pixel data in the texture cache of the GPU in response to the second instruction. The pixel data may include one or more pixel values. The method may include filtering, by the texture engine, the pixel data stored in the texture cache using the retrieved filter coefficients.

Abstract: This disclosure is directed to techniques for performing GPU-accelerated path rendering. A GPU is described that is configured to receive data indicative of a path segment of a path to be rendered, tessellate the path segment into a plurality of primitives, and render at least one of a fill area and a stroke area for the path segment based on the plurality of primitives. The techniques of this disclosure may be used to improve the performance of path rendering operations, to reduce memory bandwidth requirements needed to perform path rendering operations, and/or to reduce the memory footprint needed to perform path rendering operations.
